Selenium WebDriver is a browser automation tool which provides a lightweight and elegant way for testing web apps. Selenium WebDriver is now available as an SDK extra in the Android SDK, and supports 2.3 (Gingerbread) and onwards!

Whether or not your site is optimized for mobile browsers, you can be sure that users will be accessing it from their phones and tablets. WebDriver makes it easy to write automated tests that ensure your site works correctly when viewed from the Android browser. We'll walk you through some basics about WebDriver and look at it in action.

WebDriver Basics

WebDriver tests are end-to-end tests that exercise the web application just like a real user would. WebDriver models user interactions with a web page such as finger flicks, finger scrolls and long presses. It can rotate the display and interact with HTML5 features such as local storage, session storage and the application cache. Those tests run as part of an Android tests project and are based on Junit. They can be launched from Eclipse or the command line. WebDriver tests can be wired with a continuous integration system and can run on phone and tablet emulators or real devices. Once the test starts, WebDriver opens a WebView configured like the Android browser and runs the tests against it.

WebDriver is an Android SDK extra and can be installed following these instructions. Once you've done that you'll be ready to write tests! There is a comprehensive WebDriver user guide on the Selenium site, but let's start with a basic example using www.google.com to give you a taste of what's possible.
